SYRINGE.

Application filed etober 22, 1917.

T0 all whom t may concern Be it known that l, WILLIAM C. SEITz, a citizen of the United States, residing'v at Glen Rock, in the county of York and State of Pennsylvania, have invented certain new and useful ImprovementsI in Syringes, of which the following is a specification.

This invention relates to syringes, and more particularly to the type known as rectal irrigators.

The object of the invention is to so con struct a syringe of this character that it may be effectively and conveniently operated in a comfortable and natural manner, and by the use of which greater or less pressure may be given to the liquid as desired.

Another :object is to so construct a device of this 4character that the filling nozzle performs a double function being designed to operate as a filling nozzle and as a support for the injection nozzle.

With the foregoing and other objects l1n view, which will appear as the description proceeds, the invention resides `1n the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed without departing from the spirit of the invention.

in the accompanying drawings Figure 1 represents a plan view of the syringe constituting this invention, and

Fig. 2 is a longitudinal central section thereof.

ln .the embodiment illustrated, a liquid receptacle or reservoir 1 is shown, preferably a rubber bag' or ice cap of well known character, which has the usual lling nozzleJ 2 in the top thereof, apertured ears hbeing provided at opposite ends for hanging 1t up when not in use.

The nozzle 2 comprises a collar 4 having an outturned flange 5 at its upper end and around which the neck 6 which surrounds the opening in the bag is designed to fit in water-tight relation, being secured thereto in any suitable manner. The closure for this collar comprises a hollow plug 7 which has threaded engagement with the collar e and is provided with a laterally extending flange 8 which overlaps the flange 5 of the collar and forms a cap and has a packing or gasket 9 arranged between flanges 5 and Sso that when the cap is screwed home a fluid tight Specification of Letters Patent.

connection between the closure and the collar will be provided. This hollow cap has a centrally disposed opening through which extends a stem 10 of the rubber nozzle 11. This stem is threaded through the inner wall 12 of the cap as is shown clearly in Fig. 2 and is held in operative position by a nut 13 which preferably has a washer 1i arranged between it and the inner face of the Cap. This nozzle 11 has a head 15 with a shoulder 16 at its, lower end which rests on the outer face of the cap and between which and the nut 13 the cap is firmly clamped, (see Fig. 2). An injector stem 17 rises from the head 15, being preferably made integral therewith and said stem head and shank are provided with an axial passage or opening 18 to provide for the outlet of the liquid from the reservoir 1. The outer end of the stem 17 is closed and rounded to facilitate its insertion and is provided with a plurality of radially extending perforations 19 which permit the liquid to be'sprayed therethrough when the device is in use.

The head 15 is bored through at right angles to the axial passage 18 with a tapering hole to receive a tapering valve stem `20 and the head is recessed around said opening for the washer 21 and a screw 22 which secures said valve stem in operative engagement with the head. This stem has ahandle 23 for actuatingl it. The valve stem 20 has a passage or channel 24 extending transversely therethrough and which is designed to register when the stem is turned in one direction with the axial passage 18 in the injector stem 17 so that the flow of liquid through said stem may be controlled by the user.

By so mounting and constructing these parts it will be obvious that the cap 7 will perform the double function of a. closure for the filling opening in the reservoir and also as a support for the injector stem and its controlling valve.

A seat 25 composed of any suitable .material, preferably of wood, is made of a size greater than the size of the reservoir l and is provided with a central opening 26 to receive the lilling nozzle of lsaid reservoir. A slot 27 leads from said central opening 26 out through one edge of the seat as is shown clearly in Fig. 1 and is designed to facilitate the application of the seat to the bag when ready for use, it being understood that this slot will permit the seat to be inserted over the nozzle and the stem 20 to be passed readily through said slot.

In the use of the device, withthe reservoir containing a suitable liquid which is placed on a solid support, preferably the solid bottom of a chair, and after placing the seat' 25 thereover and the injection stem 17 inserted in the rectum for flushing the same, the said stem is held in its proper position by the natural restriction oi contractile action of the spinchter muscle. Personal weight upon Vthe seat is the motive power which forces the liquid or fluid employed for flushing purposes into the rectum or-colon without physical effort on the part of the user. The quantity of liquid injected is regulated by the operation o-f the valve stem 20 and the force employed is controlled by personal weight placed upon the seat. It is to be understood that the injector stem 17 here shown is interchangeable with other forms which may be employed for equivalent uses.

It is of course understood that when the device is not in use that the seat 25 may be removed and after the reservoir has been emptied it may be hung up or put away in the usual manner.

It willv thus be seen that this rectal irrigator which is designed to Hush the rectum and sigmoid flexure or the storing pouch of the large bowel will relieve it of any accumulations which, would tend to collect in the colon. y

From the foregoing description taken in connection with the accompanying drawings, the advantages of the construction and of the method of operation will be readily apparent to those skilled in the art to which the invention appertains and while I have described the principle of operation of the invention together with the device which I now consider to be the best embodiment thereof, I desire to have it understood that the device shown is merely illustrative and l that such changes may be made as are within the scope of the claimed invention.

I claim A syringe of the class described comprising; a flexible substantially fiat liquid container having a filling nozzle in its upper face, a detachable closure therefor, a hollow injection stem extending through said elo sure secured thereto and commnnicating` with the interior of the container, a bore extending transversely through said stem, a valve rotatably mounted in said bore with an aperture extending transversely therethrough to register with the interior of the stem when turned in one direction and to cut off registration when turned in the oppo site direction, a stem extending from said valve, and an annular plate disposed on said receptacle and surrounding said nozzle, said plate having a slot extending radially from its central opening through its perimeter, said slot being of a width to permit the passage of said valve stem between the side walls thereof to facilitate the application of the plate to the container.

In testimony whereof I affix my signature in presence of two Witnesses.
